Itching everywhere!

Alicia
I've had this consistent itching everywhere on my body for a little over a month now. Been the the hospital twice. They thought I was allergic to nicotine so I quit smoking about 2 weeks ago. I still get the intense itching all over. Literally every single part of my body itches. I just found out last week that I'm pregnant. Not sure how far along yet. Could the itching be related to that or any ideas on what could be causing it?
